So far, so good. Tiger is a 30 month old mini schnauzer. We have had him in the show ring off and on over the last 18 months... He has been growing a new jacket after a stripping in May. So far the coat looks excellent. Harder and darker than the last coat. He has only been on the probiotics and enzymes for about 3 weeks! I have also already noticed less flakiness to his skin. I have to rake and stone his jacket and he usually danders up, but NOTHING in the last two weeks. He likes the taste and has no problem eating the tabs. The most pronounced change is the dog poop. It had a most foul smell. Well, that is gone! Really strange. I guess it is a product of more complete digestion. We have lost many minis over the years to pancreas and other digestive disorders so we decided to start Tiger on these supplements young and carry him through his life. We WILL be reordering.
